GAS-BURNER.

SPECIFICATION forming part of Letters Patent No. 694,287, dated February25, 1902. Application filed July 23,1901. Serial No. 69,400. on model.)

To aZZ 1072 0121, it burg concern.-

Be it known that I, PETER KRIEs, a citizen of the United States,residing at Baltimore city, in the State of Maryland, have in ventedcertain new and useful Improvements in Gas- Burners, of which thefollowing is a specification. 4

My present invention pertains-to improvements in gas-burners, theconstruction and advantages of which will be hereinafter set forth,reference being had to the annexed drawings, wherein Figure 1 is a sideelevation, partly in section, of the burner; Fig. 2, a transversesectional View on the line 1 1 of Fig. 1; Fig. 3, a plan viewillustrating one position of the burner, the mantle-support, and mantle;and

Fig. 4;, a similar view illustrative of the action of the parts underlateral deflection.

As is well known to those conversant with the practical use ofincandescent mantles the life thereof is materially shortened and attimes the mantle entirely destroyed by being subjected to jars orvibrations, which of necessity it will meet with in various positions.'The fragility of the mantles precludes their use to a greater or lessextent in many places-such, for instance, as in portable burners. Whenused for street-lighting, the mantles will often break, the breakagebeing due to the vibrations incident to the passing of heavytrucks,cars, or the like.

The object of this invention is 'to provide a simple and effective meansfor so supporting the mantle as to relieve it from practically all jaror vibration, and as a consequence to materially lengthen its effectivelife. With this end in View I provide a structure wherein the mantle isheld in a balanced position over the burner or gas-supply tube, so thatthe burner or tube may move up or down or sidewisein any directionwithout imparting its motion to I tip freely in any direction oneindependent the mantle.

In practical use the mantle may move slightly; but the motion, if therebe any at all, will be so slight andso gradual and gentle that themantle is not aifected injuriously.

Referring tothe drawings, A designates the base or body of the burner, Bthe gas-supply tube extending upwardly therefrom, and O the usualgallery or chimney support. These ;parts may be of any type, those shownbeing theordinarycommercialform. Surrounding the upper port-ion of thegas-supply tube Bis a second tube or sleeve 'D, carrying at its upperend a gauze or foraminous cap or cover E and forming the usual Bunsenburner. Member D is of such internal diameter that it may move freely upand down with reference to tube B, and said parts may have a relativemovement from their normal vertical alinementthat is to say, one may berocked or tilted sidewise without of necessity moving the other part.Tube or sleeve D carries the mantle-support F, from which is suspendedthe mantle G. Connected to the body of the tube or sleeve are arms H, bypreference three in number, the arms extending downwardly and outwardlyfrom the tube. A series of levers are fulcrumed on the gallery, theinner end I of each lever being connected to the lower end of thecorrespondingarm' H byalink J. The

outer end K of each lever is screw-threaded and has mountedthereonaweight L. In the construction illustrated a ring or wire M formsthe pivotal support for all the levers, the ring resting against theinner face of the galleryand soldered thereto, if so desired. Thegallery is cut away or slotted to permit the levers to passtherethrough, as will be readily understood.

The parts are so proportioned and arranged that the outer ends of thelevers will stand in the position indicated in Fig. 1, wherein it willbe noted that the outerends of the levers stand just to one side of thevertical, and this is brought about by the form given to the levers andalso the adjustment of the weights to counterbalance the tube or sleeveD and the mantle.

As above noted, it is preferred to employ three levers, and these shouldbe equidistanitly spaced around the burner. By so doing the sleeve D orthe tube B may rock or of the other when a force is exerted thereon, andyet come back to its proper position immediately the cause of movementis removed. This is illustrated in Fig. 4. So, too, the parts may moveup or down relatively and be brought back to their normal position bythe weighted levers. The tube or sleeve D is shown in a depressedposition in Fig. 3. It will of course be understood that the parts ICOmay partake of motion which is both lateral and up or down, theconnections shown permitting this and at all times acting to bring theparts back to their normal positions.

If necessary, the lower end of the tube or sleeve D may be weighted, asat W, to counterbalance the weightsof the levers.

The construction is such that the fragile mantle may be employed in manypositions where otherwise its use would be found impracticable. Forstreet use'it will relieve the mantle from those constant and suddenshocks to which it is subjected Where there is heavy traflic. Inportable lights its use will be found highly advantageous.

As will be readily appreciated, there are no springs to break or set, noliquid seals with their attendant expense and complicationsin fact,nothing which can get out of order, but a construction which is simpleand efficient in its action.

the upper end thereof; a series of Weighted levers carried bya fixedportion of the burner; and connections intermediate said levers and thesleeve.

2. In a gas-burner, the combination of a gas-supply tube; a sleeveloosely encircling the upper end thereof; a mantle supported by saidsleeve; and connections substantially such as described intermediate thesleeve aud a fixed portion of the burner permitting the tube and sleeveto move universally one relatively to the other when subjected to jar orthe like, and to return the parts to their normal position.

3. In a gas-burner, the combination of a gas-supply tube; a sleeveloosely encircling the upper end thereof; a mantle supported by saidsleeve; and a series of weighted levers flexibly connected to the sleevean d fulcru med on a fixed portion of the burner.

4. In a gas-burner, the combination of a gas-supply tube; a sleeveloosely encircling the upper end thereof; a mantle carried by saidsleeve; arms connected to the sleeve and extending downwardly therefrom;a series of levers fulcrumed upon a fixed portion of the burner;flexible connections intermediate the inner ends of said levers and thearms; and a weight adj ustably mounted upon the outer end of each lever.

5. In a gas-burner, the combination of a gas-supply tube; a mantle;means for suspending said mantle over the tube; and a series of weightedlevers flexibly connected to said supporting means, whereby the tube maybe tipped laterally or moved up and down independent of any movement ofthe mantle.

6. In a gas-burner, the combination of a gas-supply tube; a sleeveloosely encircling the upper end thereof, and free to rock or tip and tobe moved up and down independently of the tube; a mantle supported bysaid sleeve; a series of arms connected to the sleeve and extendingdownwardly therefrom; a series of lovers fulcrumed upon a fixed portionof the burner; links connecting. the inner end of each lever to oneofthe arms; and a weight adjustably mounted upon the outer end of eachlever.

7. In a gas-burner, the combination of a gas-supply tube; a sleeveloosely encircling the upper end thereof; a mantle supported by saidsleeve; a series of arms connected to the sleeve and extendingdownwardly therefrom a gallery surrounding the tube; a series of leversfulcr'umed on the gallery in line with the arms; links connecting theends of the arms and the inner ends of the levers; and a weightadjustably mounted upon the outer end of each lever.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
